Merge tag ' https://github.com/oupton/linux tags/kvmarm-6.3' from into kvmarm-master/next
Merge Oliver's kvmarm-6.3 tag:
KVM/arm64 updates for 6.3
- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place.
- Add support for taking stage-2 access faults in parallel. This was an
accidental omission in the original parallel faults implementation,
but should provide a marginal improvement to machines w/o FEAT_HAFDBS
(such as hardware from the fruit company).
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception handling
and masking unsupported features for nested guests.
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM.
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at reducing
the trap overhead of running nested.
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems.
- Avoid VM-wide stop-the-world operations when a vCPU accesses its own
redistributor.
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
in the host.
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add myself as
co-maintainer
This also drags in a couple of branches to avoid conflicts:
- The shared 'kvm-hw-enable-refactor' branch that reworks
initialization, as it conflicted with the virtual cache topology
changes.
- arm64's 'for-next/sme2' branch, as the PSCI relay changes, as both
touched the EL2 initialization code.
